Hi Suzanne,
There are seversal possibilities. Are you logged in as Administrator when activating the software?
What is the exact message you're getting and the steps you're following?
Did you previously have a beta version of Office 2007 installed?
=============
I downloaded Office Pro 2007 Trial -- Won't activate even after 3 tries. It
asks me to activate EVERY time I open a program and ALL docs are locked and
unuseable. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Website e-mail tech support
option won't accept the product ID, therefore I cannot contact tech support.
HELP!!!!!!!!!!!!!!!!! >>
